Overview
The THS4130IDRG4, produced by Texas Instruments, is part of the THS413x family of fully differential input/output amplifiers. These amplifiers are fabricated using Texas Instruments' state-of-the-art, high-voltage, complementary, bipolar process. The THS4130IDRG4 is designed to provide a true, fully differential signal path from input to output, offering high supply capability up to ±15 V. This design ensures excellent common-mode noise rejection performance (95 dB at 800 kHz) and low total harmonic distortion (−102 dBc at 2 V PP, 250 kHz). The wide supply range enhances the headroom and dynamic range of high-voltage differential signal chains without the need for additional amplifiers for each polarity of the differential signal. The device operates over a wide temperature range of –40°C to +85°C.
